The Nobodies are dark creatures that are the result of strong-willed people becoming the Heartless, they are the empty shell that is left behind after the hearts are taken. They first appear in Kingdom Hearts: Chain of Memories. The inhabitants of Castle Oblivion, are all Nobodies, though this is not discovered until the second game. In the second game they become a common enemy that is faced, like the Heartless, however, the Nobodies do not have human forms like the members of Organization XIII. Each Nobody (ノーバディ Nōbadi) is generally more powerful than a Heartless creature, the more a Nobody looks like their original self, the more powerful they are. They also primarily lived in their homeworld called the World That Never Was.
